在身份验证后强制重建SOAP-Header

我的SOAP-Server希望每个请求在soap-header中都有一个有效的令牌来验证soap-client。此令牌仅在一段时间内有效,因此我不得不期望它在每次通话中都无效。

在尝试使用SOAP-Server进行身份验证后,我试图找到一种方法来强制savon重建SOAP-Header(即使用新的auth-token)。我不确定,如果这是一个savon问题或红宝石问题。这是我到目前为止所拥有的。

class Soapservice
  extend Savon::Model

  # load stored auth-token
  @@header_data = YAML.load_file "settings.yaml"

  client wsdl: 'locally-cached-wsdl.xml', 
    soap_header: {'verifyingToken' => @@header_data}

  operations :get_authentification_token, :get_server_time

  # request a new auth-token and store it
  def get_authentification_token
    response = super(:message => {
        'oLogin' => {
            'Username' => 'username', 
            'Userpass' => 'password'
        }
    })

    settings = {
      'UserID' => response[:user_id].to_i,
      'Token' => response[:token], 
    }

    File.open("settings.yaml", "w") do |file|
        file.write settings.to_yaml
    end

    @@header_data = settings
  end

  def get_server_time
    return super()
    rescue Savon::SOAPFault => error
      fault_code = error.to_hash[:fault][:faultstring]
      if fault_code == 'Unauthorized Request - Invalide Token'
          get_authentification_token
          retry
      end
  end
end

当我打电话

webservice = Soapservice.new
webservice.get_server_time

使用无效令牌,它会重新验证并成功保存新令牌,但retry不会加载新标头(结果是无限循环)。有什么想法吗?

我在这里添加了rubiii answer from the GitHub-Issue以供将来参考:

class Soapservice

  # load stored auth-token
  @@header_data = YAML.load_file "settings.yaml"

  def initialize
    @client = Savon.client(wsdl: 'locally-cached-wsdl.xml')
  end

  def call(operation_name, locals = {})
    @client.globals[:soap_header] = {'verifyingToken' => @@header_data}
    @client.call(operation_name, locals)
  end

  # request a new auth-token and store it
  def get_authentification_token
    message = {
      'Username' => 'username', 
      'Userpass' => 'password'
    }
    response = call(:get_authentification_token, :message => message)

    settings = {
      'UserID' => response[:user_id].to_i,
      'Token'  => response[:token], 
    }

    File.open("settings.yaml", "w") do |file|
      file.write settings.to_yaml
    end

    @@header_data = settings
  end

  def get_server_time
    call(:get_server_time)
    rescue Savon::SOAPFault => error
      fault_code = error.to_hash[:fault][:faultstring]
      if fault_code == 'Unauthorized Request - Invalide Token'
        get_authentification_token
        retry
      end
  end

end

rubiii补充道:

  

注意我删除了Savon :: Model,因为你实际上并不需要它,我也不知道它是否支持这种解决方法。   如果查看#call方法,它会在每次请求之前访问并更改全局变量。
